docs(meta): D-226 T-1124 amendment — windowed district-resolution regional map design (T-1124)
Five sections, Tyre data shape + Araminta screen/encoding (T-1112
pattern): (1) request = serde-default window_center/window_n ON
AtlasLayerRequest (five-shape demux cap honored); (2) response carrier
RULING — district_window is a windowed viewport query keyed
(body, center, n) with echoed-center staleness guard, deliberately
OUTSIDE the dense whole-body layer family whose growth ceiling is
re-scoped (not busted) to that family; (3) six per-cell fields incl.
glaciation_grade (T-1127 deferral accepted) and Marine-exhaustive
vegetation; (4) binding budget — 7 bytes/cell, MAX_N=64 (~28 KiB),
DEFAULT_N=32, temp shares the T-1118 region-ramp colorizer across zoom
levels (D-243 continuity), pan-only re-request (zoom never refetches),
D-227-determinism client cache; (5) screen — zoom-threshold LOD swap
in the existing AtlasViewer, morphology base with elev_q lightness,
gen_dw_* toggles, glaciation as always-on tint modifier, Marine
transparent, implant chrome discipline.
Validated via pql decisions validate. Implementation is follow-up
ticket scope (server wiring must resolve the named TerrainAnalysis
transience decision; client screen).
